I'm on chapter 10 right now, and it doesn't seem like it's going to be addressed. It sort of appears as if Marx's entire elaborate system falls apart upon its inquiry. I'm also reading "Companion to Capital" by Harvey, and "Reading Capital" by 'various'. Here it is:
To Marx, the value of the commodity labor-power is the value of the means of sustenance required to reproduce it on the part of the laborer. OK. He also says that the use-value of labor power is labor, i.e., the consumption of laborpower by the capitalist to whom it is sold is the laboring of the labourer (or the capitalist's being able to boss around the labourer to do this), who, in this act, can originally produce (ignoring the "metempsychosis" of the value of the MoP) more value than labor-power is valued at. The difference between the latter and the former is surplus-value. But, why is this possible? How can this non-equivalence occur? It's because, to Marx, the value of laborpower (the commodity) is the value of the means of sustenance required to allow him to 'reproduce himself' DAILY. My question is, isn't Marx wrong here?
The value of a commodity is always the amount of socially neccesary labor-time congealed in that commodity, and never more or less. So the value of labor-power is the value of the MoS required to reproduce that amount of labor power only. But then the labor-power is consumed, and its use-value, labor, not only reproduces the value of the labor-power but also produces surplus-value. But shouldn't the MoS whose value determines the price of labor-power be that amount/type/whatever of sustenance which allows the laborer to labor only for the amount of time needed to reproduce the value of his labor-power?
That's to say that, the commodity "labor power" isn't some mephistophelian contract. It is a quantitative thing, right? So its value should be the value of the MoS which can reproduce the amount of labor, specifically, which its consumption is, or which its use-value is, not some vague "daily" amount of labor-time. "labor power"'s use-value is labor for a certain quantity of time, so the MoS which reproduce labor-power should be only that amount which gives the laborer the 'vital energy' to perform that amount of labor: the same amount of labor which went into producing, and which could produce, if employed to do so, the MoS required to reproduce it. Shouldn't surplus value not exist at all? (I'm not here to explain profit, just to question Marx using his own rules.) Any labor performed which produces value above and beyond that of labor-power should require more MoS to perform, and so should be accounted for in the value of the labor-power sold. Labor isn't something distant from labor-power; the former literally IS the latter in action. The MoS which produce the latter should only be that MoS which lends to the former enough "vital energy" to reproduce the value of the latter.
So, to recapitulate, to Marx:
labourer sells labor-power at market for the value of the means of sustenance required to vitalize labourer ➛ labor-power bought and consumed by captalist ➛ labourer labors so as to reproduce value of labor-power ➛ labor labors even more, so as to create surplus-value
to notorious political economist and philosopher Me:
labourer sells labor-power at market for only the value of the means of sustenance required to vitalize the labourer only for that amount of laboring-time he is going to undertake ➛ labor power bought and consumed by capitalist ➛ labourer labors so as to reproduce value of labor-power ➛ he hasn't the energy to labor more; he has the energy to live and go home and relax and stuff more, but not to continue laboring, because the value of something is the labor neccesary to produce it, and that 'something' is the labor-power for a specific number of hours' laboring, so the means of sustenance, whose value is the value of labor-power, should only be that quantity and quality of sustenance which gives the labourer the strength to labor for some hours and just live until the next day otherwise
I don't know if I've communicated my objection clearly enough. Maybe it's nonsense, and I'm in over my head– this is pretty muddy stuff. (Marx's repetitive fucking jargon doesn't help. He clearly wanted as little people as possible to be Marxists.) Attempting to write this post has only made me doubt myself even more. Anybody got an answer?
